Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Guzmania hybrid.

Variety denomination:

The inventive variety of Guzmania disclosed herein has been given the variety denomination ‘DURAMIA’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2017/1808, filed Jul. 18, 2017, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The Guzmania variety ‘DURAMIA’ is an F1 hybrid seedling selection which resulted from a controlled pollination breeding program. In May of 2004, the inventor performed the controlled cross-pollination of Guzmania hybrid ‘Depladia’ (U.S. Plant Pat. No. 13,577), the seed parent, and Guzmania lingulata ‘Magnifica’ (not patented), the pollen parent, at a commercial greenhouse in Alajuela, Costa Rica. Those skilled in the art recognize that Guzmania seed can be difficult to germinate. Therefore, in September of 2004, the seed that resulted from the cross of May 2004 in Alajuela, Costa Rica were shipped by the inventor to a tissue culture laboratory in Evergem, Belgium for in vitro seed germination in order to increase the germination rate. At the direction of the inventor, the resulting seedlings were grown for 6 months to evaluate plant vigor and the most vigorous seedlings, given the population code 8222, were then shipped back to Alajuela, Costa Rica for further evaluation by the inventor. In May of 2007, the inventor selected one seedling for further evaluation due to its unique growth habit and flower characteristics, giving the seedling the experimental code, 8222#1. This seedling was further evaluated for several years in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation this new and distinctive cultivar was given the name ‘DURAMIA’.

Asexual Reproduction: ‘DURAMIA’ was first asexually propagated by meristematic tissue culture in January of 2014 at a commercial laboratory in Evergem, Belgium and has since been asexually propagated through 3 additional generations. Through subsequent generations, the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘DURAMIA’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DURAMIA’. These characteristics, in combination, distinguish ‘DURAMIA’ as a new and distinct Guzmania cultivar:

-   -   1. Guzmania ‘DURAMIA’ exhibits a compact monopodial growth habit         with foliage arranged in an attractive rosette; and     -   2. Guzmania ‘DURAMIA’ exhibits short and broad, dark green         foliage; and     -   3. Guzmania ‘DURAMIA’ exhibits a compact inflorescence which is         positioned below the foliage plane; and     -   4. Guzmania ‘DURAMIA’ exhibits a red and yellow bicolored         inflorescence with a yellow center.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage of ‘DURAMIA’

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical inflorescence of ‘DURAMIA’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in August of 2017 describe averages from a sample set of six specimens of 18 month-old ‘DURAMIA’ plants grown in 9 cm nursery pots at a commercial greenhouse in Evergem, Belgium. Plants were grown under light maximum light levels of approximately 12,000 lux. Plants were maintained with a fertigation program and regularly watered with overhead irrigation. No chemical pest measures were taken.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘DURAMIA’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
